Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54420, here are decompositions:
- 7 + 54413 = 54420
- 11 + 54409 = 54420
- 17 + 54403 = 54420
- 19 + 54401 = 54420
- 43 + 54377 = 54420
- 53 + 54367 = 54420
- 59 + 54361 = 54420
- 73 + 54347 = 54420
Showing the first eight; more decompositions exist.
